DOUBLE-ACTING OUTWARD-PULLING WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 277,887, dated May 22,1883.

Application filed October 2, 1882. (No model.)

To all whom "a? may concern:

Be it known that I, EDWARD GoNKLIN,-oi Ghannahon, in Will county, andState of Illinois, have invented certain new and usefulImprovementsinDouble-ActingOutward-Pulling Weather-Strips for Doors, theconstruction and operation of which I will proceed to explain,referencebeing had to the annexed drawings and the letters and figures thereon,in which Figure l is an end view of the strip on the door, Fig. 2, across-sectional view of the weather-strip, and Figs. 3, 4, and 5 viewsof the parts forming the spring-joint.

This invention relates to certain improvements in weather-strips fordoors of the class that are provided with a leaf hinged to the outerface of the door near the bottom, and so arranged as to close theaperture between the door and the threshold to prevent dust, rain, orwind from passing under the door when it is closed.

. Referring to the show the door at D. I

B is a cleat attached to the outer side of the door, and provided withan overhanging or projecting hood, (1., to cover the leaf a, which ishinged, as shown in Fig. l, to the lower outer corner ofsaid cleat, sothat when the leaf it hangs perpendicularly it willfall outside thethreshold K, as shown in said figure.

drawings, Figs. 1. and 2 The leaf a is provided with a spring joint" by.means of which it is held up, as shown in Fig. 2, or down, as shown inFig. l. The springjoint consists of the stud 0, set in the cleat B, andthe plunger 0, set in the leaf a on the coilspring S, so their facesmeet, as shown in Figs. 1 and 3. The stud c has its face beveled at anangle of about forty-five degrees, and is provided with the slot 0across its face, as shown in Fig. 4, to receive the correspondingprojection, a, on the beveled face of the plunger 0.

'The resiliency of the spring S holds the plunger c in contact with thestud c with considerable force, so that when the leafa. is raised orstarted up a little the plunger and springwill carry and hold it up, asshown in Fig. 2. When the door closes, the leafa engages with a stud,'v, on the jamb A to start it down, and the action of the spring carriesthe leaf down, so that it hangs perpendicularly outside of and againstthe outer face of the threshold, as

shown in Fig. 1, so as to cause a constant pressure of the leafa againstthe thresholdby means of the resiliency of the spring S forcing the faceof the plunger 0 against the stud oin the position shown in Fig. 3, thusholding the leaf a in the position shown in Fig. 1, as is obvi ous fromthe shape of the faces of the stud c and plunger 0. The door is thusheld closed by force of the spring, as well as having the opening underthe door closed, instead its being forced a little ajar, as is the casein all that class of weather-strips where the leaf is held down bycontact against some obstruction. When the parts are in the positionshown in Fig. 2 there is a constant effort on the part of the stud c andplunger 0 to come in line with each other on accountot the contactoftheir two faces and the resiliency of the spring S. When theleafahangs down, asin Fig. 1, the stud cand plunger 0 are in the positionshown in Fig. 3, and the resiliency of the spring holds them in suchposition, as is obvious from the form of their faces. WVhen the dooropens, the leaf a drags over the threshold K, and is raised therebysufficiently to give it a start upward, when the spring-joint describedcarries it up and holds it there, as shown in Fig. 2, until its returnagainst the stud 1; causes it to return again, as shown in Fig. 1.

The leaf to maybe hinged to the 'cleat or hood above it in any manner soit will be weather-tight, and so itwilloperate in the manner described.I

Any number of such spring-joints may be used along the length of theleaf that may be necessary, or any other form of spring used that willperform the same function. By this means the space under the door is notonly closed effectually, but the door is held closed against the stopsor jamb by constant pressure of the leaf a against the outside of thethreshold in the manner set forth. The leaf a falls down to the floor orsill K against a part of the threshold that is not worn as the top ofthe threshold generally is, so that a close fit is insured to the flooror sill, as well as against the outer face of the threshold. The greatadvantage of this weather-strip over others is that the leaf a, whendown, as shown in Fig. 1, is constantly pulling the door shut andholding it tightagainst the stops orjamb instead of pushing it backwardand a trifle open, as in most other cases, so that there are openingsand cracks for the wind and dust to enter, and twisting the door out ofshape to spoil it. It is this idea or principle of holding the doorclosed by constant pulling force of the leaf or that I desire to cover,and I do not confine myself to any particular form of hinge or leaf,only so that the principle is maintained. Any kind of a hood to coverthe leaf a may be used so it will permit theleaf to operate asdescribed, and render the attachment to the door weather-tight.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is as follows, to wit: H

1. In a Weatherstrip for doors, the leaf a, hinged at its upper edge tothe cleat B, and provided with the spring-joint, consisting of the studc, plunger 0, and coil-spring S, where- 20 by the resiliency of thespring S holds the leaf a either up or down, as and for the purpose setforth.

2. In a weather-strip for doors, the combination and arrangement of theleaf a, spring 25 S, plunger 0, stud a, hood a, cleat B, and hinge H,with the door D, as and for the purpose set forth.
